Suvorova, V. Bykova, V. Andreeva, V. Medvedev, A. Serkov] Conclusions: -- A phase-equilibrium diagram has been obtained for the system polyacrylonitrile-dimethyl sulfoxide-isopropyl alcohol, which permits one to determine the composition of phases in the isolation of polymer from solution. -- It has been shown that the precipitation thresholds decrease with increase in the isopropyl alcohol content of the precipitation bath and with increase in polymer concentration in the spinning solution. -- The correlation has been shown between the change in structure parameters of polyacrylonitrile isolated from solutions by the wet method and the polymer precipitation conditions, which are characterized by the concentration of the starting solution and the composition of the precipitation baths.
